Enterprise Blockchain Strategy, Implementation, and Operations
What this domain tests
Strategy, platform selection, implementation, and run operations. Expect questions on the value case, PoC-to-production gates, and the operating model.
Core rules
- Build the business case around a measurable pain: reconciliation cost, settlement delay, dispute rate, audit effort, or working capital.
- Choose according to requirements: privacy, throughput, finality, identity, smart-contract language, hosting, and vendor support. Fabric suits permissioned data partitioning; Corda suits bilateral agreements; EVM chains suit Solidity reuse.
- A PoC is not production. Gate on security review, performance under realistic load, integration, legal sign-off, operating model, and consortium commitment.
- Operations include node monitoring, certificate renewal, chaincode upgrades, backups, disaster recovery, capacity planning, incident response, and SLAs.
- Plan the exit: data extraction, member departure, network wind-down, and escrow of keys.
Worked example
A retailer traceability PoC works with three suppliers. Production requires 200 suppliers, EDI integration, GS1 identifiers, certificate rotation, 24/7 monitoring, and a dispute process. The team gates launch on a load test at peak recall volume and a signed data-sharing agreement. The reasoning: the technical demo does not prove the network effect or the operating cost.
Traps
Do not confuse a pilot with a product. Do not underprice ongoing operations and key management. Do not select a platform by hype. Do not launch without an exit and data-portability plan. Do not ignore change management for legacy teams.
